If Black Bears were brought into a tropical enviroment, could they grow larger and stronger?

Answer 1

i hear that nothing can stop a bear. bad a$$ bears. go to youtube and search for bears fighting other animals. there's one where a bear takes down a caribou in a river, drowns the $hit out of it and then eats it. wow. it's called "bear vs caribou" i think

Answer 2

They could, assuming they could find sufficient food, water, shelter and other black bears with which to mate and make other black bears.

If there were selective pressure that led to greater reproductive success for larger and stronger tropical black bears, then they could indeed become larger and stronger. One possible selective pressure that might cause this adaptation would be competition with other tropical carnivores that already exist in the tropics.

If the black bears had to compete with jaguars or maybe sun bears for their meals, it might be the big, strong ones that are successful in fighting off the competition and pass on their big, strong genes to the baby tropical black bears.

It's also possible that competition and environmental stress kills off the black bears before they get established, and the population doesn't survive.

Answer 3

Simply moving the black bears to the tropics may allow for environmental factors to affect the bear in producing more muscle mass, if the area provided better nutrition for the bears, but this is based on environmental factors only, so would not be heritable in the black bears offspring. Only by natural selection, mutations in the black bears genome for increased strength, and the selection of that mutational factor could black bear populations actually evolve. Check up on Darwin's four postulates of natural evolution.

Answer 4

I doubt it. They would certainly change over many years and become something other than a black bear. But if anything they would grow smaller and weaker, there would be no reason for them to grow larger.

Answer 5

They would probably become smaller in the tropics.

Remember, the world's largest bears are the Kodiak bears in Alaska and the polar bears in the Arctic. They are much larger than their warmer weather cousins in even temperate climates.

Answer 6

No, but in a span of time, they would evolve smaller in size. The bears in tropics are smaller in size and the hair on their body decreases.
Because, see the thing (size of bears arranged in decreasing order)
siberian bear>brown bear>black bear>giant panda>other bears
is equal to
polar>alpine>temperate>between temperate and tropics>tropical and equatorial

Answer 7

black bears use to live in the tropics, but then the white polar bears took them from their homeland and made them their slaves.

Answer 8

There are black bears in Florida, and they're not really big.

Answer 9

if you believe in evolution and situal awareness yes they most deff could, as long as there is a food source for them

Answer 10

absolutely, there are healthier food and berries there. it has also been said many chemicals of steriods are there.
